ROLLER-BEARING.

SPECIFICATION forming part of Letters Patent No. 776,773, dated December6, 1904. Application filed June 25, 1904. Serial No. 214,119. (Nomodel.)

To all whom, it may concern:

Beit known that I, THoMAsALBERT BLAKELY, of Flesherton, 1n the county ofGrey and Province of Ontario, Canada, have invented certainV new anduseful Improvements in Roller-Bearings; and I hereby declare that thefollowing is a full, clear, and exact description of the same.

This invention relates to certain new and useful improvements in thatclass of rollerbearings in which the bearing-rollers are journaled inannular bearing-rings tied together and revoluble around the shaft, andit relates more particularly to the peculiar construction of thebearing-rollers and annular retaining-rings and the means-whereby thebearing-rollers are journaled therein, the object of the invention beingnot only to reduce the frictional contactI between the journals of thebearing-rollers and their bearings in the annular retaining-rings, butalso to absorb the end thrust of the rollers.

In carrying' out these objects the annular retaining-rings are providedwith a series of equispaced ball-apertures so arranged that theball-apertures of one ring aline with those of the other, and theserings are rigidly fastened together by bolts or rivets having abuttingshoulders to engage the inner surfaces of the rings and hold them evenlyspaced. Contained between the annular retainingrings are antifrietionbearing.- rollers and formed in the ends of the antifrictionbearing-rollers are concaved recesses to receive the antifriction-ballswhich enter the apertures in the retaining-rings and constitute themeans whereby the bearing-rollers are journaled therein.

For a full understanding` of the invention reference is to be had to thefollowing' descripi tion and to the accompanying drawings, in

which- Figure 1 is a sectional View of a shaft and hub, showing theroller-bearings therefor. Fig. 2 is a perspective view of thebearingrollers and retaining-cage. Fig. 3 is a perspective View of oneof the bearing-rollers looking at it from the end. Fig. 4 is a seetionalview on the lines a d, Fig. 2.

Like letters of reference refer to like parts throughout thespecification and drawings.

1n the center of the ends of the antifriction bearing-rollers a areconeaved recesses and contained in these recesses are antifrictionballsc, journaled in and protruding through corresponding ball-apertures (Zin the annular retainingrings e. The annular retainingrings e areseparated laterally by the abutting shoulders g of the tie-pins it,which engage their inner faces and the reduced ends of which projectthrough correspondingl apertures in the annular retaining-rings and areriveted against the outer faces of the same to hold the retaining-ringsin position, so that the ball-apertures d in the retaining-rings willaline and form the bearings for the antifriction-balls c, whichconstitute the journals of the bearing-rollers. Loosely mounted on theaxle on the outer faces of the retainingrings e are antifriction-washersf/ to contact the protruding parts of the antifrietion-balls. Thebearing-rollers `lit loosely between the inner faces of theretaining-rings and project slightly beyond the inner and outer edgesthereof, so as to engage the bore of the hubj, which is loosely mountedupon the axle and. held from contact therewith by the bearingrollers a.Mounted upon the axle on the outer sides of the hub j are adjustablecollars l, which engage the outer surfaces of the antifrietion-washersand lock them in position against the ends of the antifriction-balls, soas to maintain the antifrietion-balls in position while formingarollingcontact therewith. .In the operation of the apparatus the hub andthe axle engage the antifrietion bearingrollers during the independentrevolution of the hub upon the bearing-rollers and the combinedrevolution of the bearing-rollers and retaining-rings around the shaft,the ends of the bearing-rollers revolving against the antifriction-ballsas they revolve -in their bearings in the retaining-rings, the frictionof the revolution of the bearing-rollers being minimized by theirrolling contact with the balls and the rolling contact of the balls inthe ball-apertures of the retaining-rings.I The end-thrust motion of thebearing-rollers is absorbed by the antifriction-balls and theantifriction-Wasliers and is resisted by the adjusting-collars mountedupon the shaft.

It is not desired to coniine the use of the invention exclusively to oneparticular bearing, as I may employ it for any revoluble device which isloosely mounted on a shaft, or I may use it in conjunction with a shaftrevoluble in a stationary bearing in which it is necessary to providefor end-thrust motion as Well as for its comparatively frictionlessrevolution.

Havingthus fully described my invention, what I claim as new, and desireto secure by Letters Patent, is-

In a roller-bearing the combination of a stationary shaft, annularretaining-rings loosely
